Trump moves to end federal studies on rocket and satellite pollution, raising concerns over Musk’s influence
The Trump administration plans to shut down research led by the National Oceanic and Atmospheric Administration (NOAA) into pollution from satellites and rockets that is tied in part to Elon Musk’s expanding space ventures.
Tom Perkins reports for The Guardian.
In short:
- The administration aims to halt two NOAA projects studying how metals and other emissions from spacecraft accumulate in the stratosphere, potentially harming the ozone layer and climate stability.
- Critics argue the cuts, justified by officials as removing “woke ideology,” will benefit Musk’s SpaceX and Starlink, which dominate satellite launches and could face future regulations stemming from such research.
- Scientists warn that with 100,000 satellites expected in orbit within a decade, unchecked pollution could disrupt stratospheric chemistry and temperature regulation, yet little independent monitoring will remain if the projects end.

Why this matters:
Rocket launches and satellite operations introduce pollutants — including aluminum, black carbon, and nitrogen oxides — into the stratosphere, an atmospheric layer critical to shielding Earth from harmful solar radiation and maintaining climate balance. As the commercial space race accelerates, thousands of new satellites from companies like SpaceX and Amazon could exponentially increase this pollution. The aluminum particles, in particular, pose dual threats: While they might reflect sunlight and cool the planet, they could also disrupt the delicate chemistry that governs stratospheric temperature and ozone health. Without federal research, understanding these impacts will fall largely to the industries driving the pollution — a clear conflict of interest.
